Aerial spraying will continue over a period of several evenings until all areas noted in the red border on the state map has been completed. Please visit the Massachusetts Aerial Mosquito Spray Map at https://massnrc.org/spray-map/MidWorNorSept2019.htm. Note: To see exactly which parts of the map were sprayed each night, please check back on the afternoon following the spray. The map will be updated as soon as the data is available. All scheduled spray are tentative as it's highly dependent on weather patterns and could change at the last minute.
Date of Record - September 10, 2019
A second round of aerial spray is tentatively scheduled for this evening starting around 7:15 PM to take advantage of warmer weather in portions of Eastern Worcester, Middlesex and Norfolk Counties to assist in lowering risk of human infection of EEE. It is important to note that all spraying is tentative and is highly dependent on weather patterns. Residents are encouraged to plan for an aerial spray this evening but plans could change at the last minute.
It remains critically important for people in communities at critical, high and moderate risk for EEE to continue to take personal precautions against mosquito bites. These steps include using EPA-approved bug spray, wearing long sleeves and pants outdoors to reduce exposed skin, and cancelling outdoor activities in the hours from dusk to dawn when mosquitoes are most active.

All residents throughout the Commonwealth should continue to use mosquito repellent and those in high and critical risk communities should consider staying indoors during the dusk to dawn hours to reduce exposure to mosquitoes. Residents can learn more about EEE and about ways to protect themselves on DPH’s website.
Spraying for mosquitoes does not eliminate the risk of EEE transmission and the public is asked to continue to follow personal protection practices. People have an important role to play in protecting themselves and their loved ones from illnesses caused by mosquitoes. Please continue practicing the 5D's (Drain, DEET, Dawn/Dusk, Dress).
Avoid Mosquito Bites - Apply Insect Repellent when Outdoors. Use a repellent with an EPA-registered ingredient (DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] or IR3535) according to the instructions on the product label. DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age.
Be Aware of Peak Mosquito Hours. The hours from dusk to dawn are peak biting times for many mosquitoes. Consider rescheduling outdoor activities that occur during evening or early morning in areas of high risk.
Clothing Can Help Reduce Mosquito Bites. Wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
Mosquito-Proof Your Home - Drain Standing Water. Mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by draining or discarding items that hold water. Check rain gutters and drains. Empty unused flowerpots and wading pools and change the water in birdbaths frequently.
Install or Repair Screens. Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.
Protect Your Animals - Animal owners should reduce potential mosquito breeding sites on their property by eliminating standing water from containers such as buckets, tires, and wading pools – especially after heavy rains. Water troughs should be flushed out at least once a week during the summer months to reduce mosquitoes near paddock areas. Horse owners should keep horses in indoor stalls at night to reduce their risk of exposure to mosquitoes. Owners should also speak with their veterinarian about mosquito repellents approved for use in animals and vaccinations to prevent WNV and EEE. If an animal is suspected of having WNV or EEE, owners are required to report to DAR, Division of Animal Health by calling 617-626-1795 and to the Department of Public Health (DPH) by calling 617-983-6800.
